[James R. L. <jl...@mi...>]

First thing, thank you for taking time to download and look at ldp-portable.
Second thing, you will want to get the latest version via CVS:

Once you have the newest version, re-read ldp_struct.txt

ldp_struct.txt is the best I have to give you to explain the relationships.
What more do you want?  It even tells you if they are 1:1 1:N or N:M!!!
From there you canm "use the source" to figure it out.

Remember that ldp-portable has to keep track of info which could be stored
in the kernel or other routing code.  It does this so that it can remain
OS/routing system independent.
